Multi-channel high-efficiency heat dissipation water-cooling radiator

ABSTRACT

A multi-channel high-efficiency heat dissipation water-cooling radiator includes a water distribution box, a water collection box, a first radiating pipe, a second radiating pipe, a third radiating pipe, and a fourth radiating pipe. Multiple chambers are formed by arranging partitions in both the water distribution box and the water collection box, and each radiating pipe is in communication with the corresponding chambers, so that the channels in the water-cooling radiator are connected in sequence to form a circuitous configuration. This allows the water to travel a longer distance in the water-cooling radiator, so that the water-cooling radiator can effectively cool the water and dissipate heat.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a radiator, and more particularly to a multi-channel high-efficiency heat dissipation water-cooling radiator.

2. Description of the Prior Art

A water-cooling radiator is configured to radiate the heat of the radiator using a liquid under the action of a pump. Compared with air cooling, the water-cooling radiator has the advantages of quietness, stable cooling, and less dependence on the environment. The heat dissipation performance of the water-cooling radiator is proportional to the flow rate of a cooling liquid (water or other liquid). The flow rate of the cooling liquid is related to the power of the pump in the cooling system. Moreover, the heat capacity of water is large. This makes the water-cooling system have a good heat load capacity.

A conventional water-cooling radiator assembly usually consists of a water-cooling radiator, a water-cooling block, and a water pipe. The water pipe is connected between the water-cooling radiator and the water-cooling block. The water pipe allows the water to circulate in the water-cooling radiator and the water-cooling block. After the water absorbs the heat from the water-cooling block, the water flows to the water-cooling radiator for heat dissipation, and the water after heat dissipation flows back to the water-cooling block.

In the prior art, the channels of the water-cooling radiator of the water-cooling radiator assembly are U-shaped. This results in that the water travels a short distance in the water-cooling radiator, so the water-cooling radiator cannot effectively cool the water and dissipate heat. Therefore, it is necessary to improve the conventional water-cooling radiator.

SUMMARY OF THE INVENTION

In view of the defects of the prior art, the primary object of the present invention is to provide a multi-channel high-efficiency heat dissipation water-cooling radiator, which can effectively solve the problem that the conventional water-cooling radiator cannot effectively cool the water and dissipate heat.

In order to achieve the above object, the present invention adopts the following technical solutions:

A multi-channel high-efficiency heat dissipation water-cooling radiator comprises a water distribution box, a water collection box, a first radiating pipe, a second radiating pipe, a third radiating pipe, and a fourth radiating pipe.

The water distribution box is made of a heat-dissipating metal material. A plurality of first partitions is provided in the water distribution box to divide an inside of the water distribution box into a water inlet chamber, a transition chamber and a water outlet chamber. The water distribution box is formed with a water inlet, a water outlet, a first installation groove, a second installation groove and a third installation groove. The water inlet and the first installation groove communicate with the water inlet chamber. The water outlet and the second installation groove communicate with the water outlet chamber. The third installation groove communicates with the transition chamber.

The water collection box is made of a heat-dissipating metal material. At least one second partition is provided in the water collection box to divide an inside of the water collection box into a first water collection chamber and a second water collection chamber. The water collection box is formed with a fourth installation groove and a fifth installation groove. The fourth installation groove communicates with the first water collection chamber. The fifth installation groove communicates with the second water collection chamber.

The first radiating pipe, the second radiating pipe, the third radiating pipe and the fourth radiating pipe are all provided with radiating fins. One end of the first radiating pipe is hermetically installed in the first installation groove and communicates with the water inlet chamber. Another end of the first radiating pipe is hermetically installed in the corresponding fourth installation groove and communicates with the first water collection chamber. One end of the second radiating pipe is hermetically installed in the corresponding third installation groove and communicates with the transition chamber.
